    Comment by PSA:   Impressive.   Very much a demonstration that
    raises questions.  Downward flows.   But mot totally downward
    (unknown percentage, to be studied)..<br>
    <br>
    And then at the end, there is a "click here" box to go to further
    work.   <br>
    <br>
    Part B.  <br>
    <br>
    That box takes you to <br>

    Same fellow.   and showing clearly UPdraft.   Side by side
    comparisons.  Well worth watching.  <br>
    <br>
    That is dated 2015.  I hope that somebody will delve into this
    further.   There is still a great deal of TLUD science to be
    researched.<br>
    <br>
    This all is (in my opinion) support for thinking the micro-gasifier
    stoves (ACS for Advanced Cookstoves) will continue to get better and
    better, further distancing them out ahead of the stick-burner ICS
    (Improved or Inadequate Cookstoves).   <br>

                      I stumbled onto this video by accident.   He is
                      instructing (64,000 views) that the air in the
                      fuel chamber of a woodgas stove (same drawings as
                      for a TLUD) are moving DOWNWARD.<br>

                      Totally bogus.<br>
                      <br>
                      I would not even mention it to the Stoves Listserv
                      except to express my disgust and to point how what
                      is creeping into information flows about stoves.<br>
                      <br>
                      Might be a nice challenge for students to try to
                      PROVE the direction of the air flows in TLUD
                      stoves.   Such as an increase in temperature in
                      the bottom few cm of the fuel if the hot gases
                      were pulled downward.    Of detecting combustible
                      gases in the gap between the fuel cylinder and the
                      outer cylinder.<br>
